Ulano Platinum is a SBQ-photopolymer direct emulsion best used for imprinted sportswear and plastisol inks. This particular emulsion is developed with anti-halation properties which allows Ulano Platinum to be used with inexpensive white mesh without losing stencil definition. High solids content and simultaneous, high viscosity, it can even be used with coarse mesh.
Durable and quality composition allows Ulano Platinum to be humidity-resistant, even in humid conditions.
Resistant to aggressive post-phthalate plastisols and many wash-up solvents.
High solids content (on average 42%) which allows Ulano Platinum to dry quickly and bind more effectively to mesh for cleaner details and more defined lines.
Can be used with auto-reclaim systems for large scale productions, and becomes water-based and discharges inks when mixed with diazo
INSTRUCTIONS FOR HANDLING & USE
It is best to coat and handle Ulano Platinum under yellow safelight in order to avoid pre-exposure.
Ulano Platinum is provided presensitized and premixed as an emulsion for plastisol inks. The addition of sensitizers, like diazo, is unnecessary.
Whether or not you are reusing a mesh or using a brand new one, it is always best to make sure that your mesh is ink, dust, and contaminant free. For used screens, simply degrease your mesh using mesh prep or a screen degreaser like Magic Mesh Prep, Screen Degreaser No. 3, or Screen Degreaser Concentrate No. 33. For a new screen that is not surface treated, using an abraser would be best for allowing the best bonding rates. To complete both processes at once, try Ulano UlanoGel No. 23. No matter what you use, make sure to rinse the screen well, and let dry before moving onto the coating process.
There are three viable methods to coat Ulano Platinum:
Method 1: Apply a coat to the printing side, and another to the squeegee side. Dry the screen thoroughly.
Method 2: Apply two coats to the printing side, then two the the squeegee side. Rotate the screen 180° after each coating.
Method 3: Conduct Method 2, and once dried, apply another two coats to the printing screen.
If Methods 2 or 3 are used, the screen must be dried horizontally with the printing side down, and at room temperature. In the event that you are using commercial-sized fans to speed up the drying process, use only filtered air, to prevent contamination, and only dry at temperatures of up to 100? (40?). Use a dehumidifier to aid the process, and prevent possible inconsistencies.
How long it will take to expose is entirely depended on the type of light, the wattage, and the method in which you chose to coat your screen (refer to the Coating Procedure section above). The provided exposure times for Ulano Platinum listed below are used with reference to 120 threads/cm. (305 threads/in.) white polyester or nylon at an exposure distance of 100cm (40 in.).
1000 watts: 30 sec (Coating Method 1), 82 sec (Coating Method 2), 112 sec (Coating Method 3)
2000 watts: 15 sec (Coating Method 1), 41 sec (Coating Method 2), 56 sec (Coating Method 3)
3000 watts: 10 sec (Coating Method 1), 27 sec (Coating Method 2), 36 sec (Coating Method 3)
4000 watts: 8 sec (Coating Method 1), 21 sec (Coating Method 2), 27 sec (Coating Method 3)
50000 watts: 6 sec (Coating Method 1), 17 sec (Coating Method 2), 22 sec (Coating Method 3)
2000 watts: 75 sec (Coating Method 1), 3 ¾ min (Coating Method 2), 5 min (Coating Method 3)
8000 watts: 19 sec (Coating Method 1), 56 sec (Coating Method 2), 77 sec (Coating Method 3)
An automated washout system, while compatible with Ulano Platinum, is not entirely necessary. After exposure, gently wet both sides of the screen with cold water. Then, spray the printing side until it is clear. Next, rinse both sides with a gentle spray until the emulsion is removed from both sides. Be sure there is no foam and are no bubbles. Any excess water on the printing side may be blotted up with unprinted newspaper.
When reclaiming your screen, use Eco-Wash 160, All-Purpose Ink Wash, or an alternative, less potent ink diluent. Any of these will help remove excess ink from your screen. Then, use Ulano Screen Degreaser Liquid No. 3 to remove any residual inks and/or solvents. If stencil removers are used, make sure they do not dry on the screen. Rinse both sides of your screen thoroughly and gently, then use a powerful spray of water to remove the remainder if necessary.
INSTRUCTIONS FOR STORAGE:
Ulano Platinum can last up to 18 months when properly stored and unopened. For screens coated in Ulano Platinum, the expiration can last up to 4 weeks at 20 - 25? (68 - 77?), but only in total darkness. Humidity and other environmental factors can cause this emulsion to expire sooner.
Extending the Life of Your Emulsion
Make sure to keep Ulano Platinum in a cool, dry, and dark area
Make absolutely positive that the lid is properly sealed before and after each use to ensure its longevity.
Keep Ulano Platinum in an area free from extreme environmental factors like humidity and heat (both of which break down the emulsion)
